1997 Buick Riviera Camshaft Position (CMP) Sensor Performance

Download 1997 Buick Riviera | Aurora, Riviera (VIN G) Service Manual DTC P0341 Camshaft Position (CMP) Sensor Performance. Circuit Description The camshaft position PCM input is produced by the ignition control module. The ICM produces the camshaft position PCM input by filtering the camshaft position (CMP) sensor pulses when the engine is running and CKP sync pulses are also being received. The PCM uses the camshaft position PCM input pulses to initiate sequential fuel injection and to determine crankshaft position for the misfire diagnostic. The PCM constantly monitors the number of pulses on the camshaft position PCM input circuit and compares the number of camshaft position PCM input pulses to the number of 18X reference pulses and the number of 3X reference pulses being received. If the PCM receives an incorrect number of pulses on the camshaft position PCM input circuit, DTC P0341 will set and the PCM will initiate injector sequence without the camshaft position PCM input with a one in six chance that injector sequence is correct.… Read More

Seville/STS/DeVille Any other GM Vehicles with the VATS or PASSKey II system (If your ignition key looks like the one pictured below.) Alright, let’s begin the madness: 1. Take your DMM, set it to measure Ohms (use the 20k setting.) Measure the resistance across the pellet of the ignition key. Place one probe on the silver part of one side of the pellet, and the other probe on the other side. Write this value down. 2. Purchase a resistor or resistors that add up to the value measured in step 1. Radio Shack is a great place to go for the resistors, heat shrink tubing, and the “bullet-style” solderless connectors.… Read More
